Interesting project by the Hasso Plattner Institute Potsdam. The software can design structures using coke bottles. It outputs the necessary 3D printable trusses, allowing the rapid construction of reliable furniture prototypes and structures.

TrussFab is an integrated end-to-end system that allows users to fabricate large scale structures that are sturdy enough to carry human weight. TrussFab achieves the large scale by complementing 3D print with plastic bottles.

Unlike previous systems that stacked bottles as if they were “bricks”, TrussFab considers them as beams and uses them to form structurally sound node link structures based on closed triangles, also known as trusses. TrussFab embodies the required engineering knowledge, allowing non-engineers to design such structures.
